12" thick walls and roof seem to be good. That takes a few weeks to get really hard. I poured 10" thick under my slab and after it dried a while I capped it with 2" of concrete encasing 3/4" pex for solar hydronic heat. In the last year and a half the wind piled sand up above the slab against the 12" thick walls, in places 18" deep or so. Once in a while on a warm day my dog Shadow will dig a hole on the shady side, and when he exposes the buried papercrete I see no deterioration. Note that I do live in an arid region about halfway between Carlsbad and Deming NM. My recipe for that project was 30# paper, 30# portland cement, and spray wash it until it is pulp and fills a 55 gallon drum. Nothing was weighed, of course. Don't worry, make slurry. Some of it was carried in buckets, some dumped directly into forms from the mixer drum on a platform. A lot was mixed in a no-tow mixer and pumped to the forms, the faster way to go.
